In Tibetan Buddhism, the Kartika, or Drigug, is a ritual flaying knife used in burial rituals, with the handle crafted as a dorje. A tool of the wrathful female deities known as Dakinis, the kartika symbolizes the cutting of all things material, symbolized by the human body. The blade is left dull (never sharpened) because it was used in a ritual representing the flaying of flesh and not for the actual purpose.
